RG'IARY PRINTING MACHINE.

Application filed December 22, 1921.

T 0 ail whom it may concern:

Be it known that 1, Joss M. Amrnom, a citizen of the United States, residing at Rock Springs, in the county of Sweetwater and State of Tl yoming, have invented certain new and useful Improvements in a Rotary Printing Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

This invention relates to a rotary printing machine particularly of the type employing manually operable rotary cylinders.

An important object is to provide a means whereby printedsheets may be delivered from a printing machine with the ink thereon substantially dry.

A second object is to effect said object by the use of an absorbent or blotting means engageable by the printed faces of the sheets during travel through the machine.

A third object is to provide means where by the paper is resiliently urgedinto effective contact with the printing cylinder and also with the blotting means and means whereby such means may be moved out of oper ative relation with the cylinders to facilitate preparation thereof.

A fourth object is to provide an improved shaft means for driving and detachably mounting the printing cylinder.

A fifth object to provide an inking means which may be carried by the printing cylinder, such a means as may be movable within the cylinder for effective cooperation with the operating surface of the cylinder, one having an operating means nor-' mally folded into the cylinder and one haw ing the inking mechanism movably mounted in the shaft.

A sixth object is to provide an improved paper table and receiving basket foldable into compact relation with the remainder of the machine and with one of said parts having means to support it and which is operable to secure the table in folded relation.

Additional objects and advantages will become apparent from. a consideration of the de'cription following taken in connection with accompanying drawings i.llus

Like reference characters designate like 'member 12 which have bearings at 13 in which a shaft 14 is journaled which supports and is adapted to impart motion to a printing cylinder 15. Cooperating with the printing cylinder 15 is a blotting cylinder 16 movable'with a shaft 17 journalejd in bearings 18 of said mounts 12. It will be noted that the mounts 12 are skeleton castings, that the bearings 13 and 18 are integral with themnounts and that they are provided with strengthening and reinforclng flanges 19. Bolts 29 may pass through the lowermost flanges 19 and'the base 10 in order to secure the mounts in place.

The printing cylinder may be of any preferred type and as shown has skeleton end disks 22 to the periphery of which is suitably fastened as at 23, a perforated cylindrical diaphragm or Wall 24. As is usual in a printing machine of this type, an absorbent inking mat 25 surrounds said diaphgram and a printing form such as a stencil or perforated flexible sheet 26 is disposed thereover. Fastened to and spanning. the disks 22 is an attaching bar 27 providedwith struck out prongs 28 on which said mat and stencil may be hooked adjacent one end. Said mat and stencil adjacent the opposite ends are turned into the cylinder and engaged by a clamping bar 2!) movable from pivots 30 on disks 22, and which binds said ends tightly but removably in place;

Shaft 14 is round and removable from the cylinder and the bearings 13. It is )rovided however with squared portions 1 which slidably but removably fit into squared openings 32 in hubs 33 of disks 22. Beyond one of the bearings 22, said shaft is provided with a crank 34 from which a horizontal handle 35 extends. A removable cotter pin or other means may pass through an opening in the shaft 14t'o normally prevent removal or displacement thereof.

Blotting cylinders may consist of a cylindrical drum 37 fastened on end disks 36 which have hubs 39. Shaft 17, except for the portion journaled invbearings 18, is pre 1'- erably square as at 40, and such squared portion passes removably through square openings 41 in said hubs 39. Said shaft 17 is also preferably removably mounted in the bearings 18 and openings 41 and it is normally held in place against displacement by means of a cotter pin 42 passing through an opening thereof.

On drum 37, a blotting and ink absorbing means, such as a blotter r ink absorbing sheet 43 is provided. This sheet is of the usualfieiiible nature so that it may conform to the shape of the drum 37 and inasmuch as it should be renewed from time to time, it is vremovably fastened. The fastening .may be accomplished in any suitable manner.

For instance, at one end of the sheet 43 reinforcirg tabs 44 are provided havmg openings therethrough adapted to fit over lugs 45 projecting from the drum. The 0 end of such sheet is also provided with reinforcing tabs 46 having openings therethrough into which securing latches 47 extend. Latches 47 are depressible so that they may engage and disengage the tabs 46. Said latches may slide through the drum 37 and. also through the brackets 38 and have an expansive spring 49 to surround the same intermediate the bracket and drum. and suitably fastened to normally urge the latches into fastening position. A manipulating arm or finger 50 projects from each latch 47 and beyond the ends of drum 37 and such arms rest on thesprings 49 so that depression of the fingers 50. will tension the springs 49 for return movement to engagement with tabs 46.

A suitable means is provided whereby the motion of the shaft 14 for printing cylinder 15 may be imparted to the blotting cylinder. To this end, I have shown a sprocket Wheel 51 rigid on shaft 13 and a sprocket Wheel 52 rigid onshaft 17 and with a,

sprocket chain 53 traversin them.

An one end of the machine, adjacent the printing cylinder 15, a suitable board or table is provided at 54 which may be mounted in any suitable manner, as by screws 55 posed.

passing through the mounts 12 and into the same. Such table 54 may have a longitudinal extension or leaf 56 adapted to be folded into compact relation against the machine and to this end preferably by a hinge as at 57 to said table 54. This leaf is also preferably provided with grooves-at 58 to accommodate the fin ers arranging the pile of paper or sheets tiereon preparatory to printing.

In order to properly guide the paper sheets to the cylinder 15, a plurality of gage members are provided. These gage members are designated 59 and have vertical Walls 60 between which the paper sheets pass. They also have lateral flanges 61 through which bolts 62 pass and above which they preferably receive their nuts 63. Said bolts pass through the table 54 and are movable laterally in elongated slots 64 so that the gages may beset at different positions according to the width of the paper and the printing form. The heads or bolts 65 are preferably square and the slots 64 are enlarged at 66 to correspond to the shape of the heads 65 in order to receive said heads and prevent turning of the bolts 62.

Disposed below the blotting cylinder 16 is a platen roller 67.' A similar platen roller 63 is disposed below the printing cylinder 16. These rollers 67 and 68 are similar and each is provided preferably with a rubbe covering or surface at 69 and 70, respectively. Said rollers 67and 68 have trunnions 71 journaled in bearings '72 preferearne s ably integral with or forming parts of le vers 73, fulcrumed as at 7 1 on brackets secured to the base. It is to be noted that the forward end of the table 51 rests on the adjacent brackets 75 to increase its support and that the adjacent upper surface of said table 54: is curved toward the roller 67 to facilitate the feed of the paper sheet intermediate said roller 67 and the cylinder 15. Springs 76, as of the coil expansive type, urged the levers 73 upwardly so rollers 67 and 68 coa-ct with an cooperate with their respective cylinders. These springs are interposed between the base and the levers 73, preferably surrounding studs or pins 77 rising from the base and extending through elongated slots 78 in said .levers 73. Two of said levers 73, overlap the remainder of said levers as at 79. As it is desirable at times to move said rollers 67 and 68 out of engagement with their respective cylinders, for instance when inking the pads or mats 25 or when attaching a new blotter 13, a suitable means to depress them is provided. To this end, a shaft 80 is journaled in the mount 12 and is provided with veccentrics or cams 81 operatively engaged with the adjacent levers 73 and which shafts 80 have an operating crank 82 provided with a handle 83. It will be obvious that upon operation of the handle 83, shaft.80 will be turned which through the medium of cams 81, and the fact that the levers 73 engage thereby overlap the other levers at 79, said cam will depress all of the levers 73 and thus simultaneously move the rollers 67 and 68 away from their respective cylinders.

Intermediate the rollers 67 and 68, a substantially horizontally disposed plate 84; is provided to guide the printed sheets from the cylinder 15 and the roller 67 to the roller 68 and blotting cylinder 16. This plate 8 1 has standards 85 depending there from and secured as at 86 to the base 10. Said shaft 80 utilizes said standards 85 as Well as the mounts, as bearings. Also rising from the plate 84 are side guard flanges 87 to prevent lateral displacement of the printed sheets as they pass thereover.

At the rear of the machine, a discharge plate 88 is provided for the printed sheets and arrange at a. point below cylinders 16 adjacent to rollers 68. Plate 88 has depending standards 89 secured at 90 to the base 10. It also has upstanding guide flanges at 91; The discharge end of said plate 88 is deflected downwardly at 92.

A basket or receptacle 93 is disposed at the rear end of the machine so as to receive the printed sheet from the plate 88. This basket may be of any suitable construction and is preferably reticulate as shown. The front end of said basket 93 is preferably hinged by means of pilots 94E tothe base end so as to be capable of folding movement against the machine as shown in dotted lines in Figure 2. The basket is supended in a horizontal position by means of book rods 95 pivoted to the basket at 96 and hav ing their forward end or hooks 97 engageable in apertures or eyelets 98 provided on the mount 12. To the undersurface of the leaf 56, eyelets 99 are provided and they project laterally beyond the side of the leaf so that when said leaf and the basket 93 are in the folded position suggested by dotted lines in Figure 2. the hooks 97 may be engaged in said eyelets 99 to hold the parts in compact relation.

Referring now to the inking device 25. it is carried by and disposed with the cylinder 15 and consists of a suitably shaped ink container or receptacle100 whose rescr voir is spanned by a transverse tube 101 through which shaft 14 passes and on which shaft it is capable of rotation. Said receptacle 100 carries a brush or applicator 102 which has applying bristles or other means 103 disposed in contact with the interior of the diaphragm 24. Said bristles extend from a head 104., which may be disposed intermediate flanges 105 on the receptacle 100 and be secured in place by screws 108 passing through said flanges 105 and into head 104. Ink may flow from the receptacle 100 through an opening 107 in its bottom and which communicates with an opening 108 in said head 104 so that the ink may flow to the applying means 103. Associated with the opening 107 is a valve 1109 of the needle type, which is operable to vary the extent of the opening and which may be carried by a rod 110 having a screw portion 111 thereon threaded into an opening 112 in the top of the receptacle 100 and also having an operating handle or portion at 113. Receptacle 100 has a filling open-v ing 114E normally closed by a closure cap 115 removably screwed in place. A stud 116 rises from the tbp of said receptacle 100 and has a vent opening 117 therethrough which may be opened or closed according to the position of a valve in the form of a lever 11.8 pivoted at 119 to said stud 116.

A loop or arched bar 120 is provided at the top of receptacle 100 and a suitable handle 121 is pivoted therefoas at, 122. .livlovem'cnt of said handle 121 to an operative position is limited by a stop or abutment 123 integral with the loop 120. Normally said handle 121 is folded toward the receptacle 100 and disposed within the cylinder 15.

v Yihile the receptacle 100 is capable of rotation on the shaft 14, yet it is normally held against movement relatively to the shaft 14 and cylinder 15. To this end. one extremity of tube 101 as at 121 has a square opening which is adapted to slidingly enslidably mounted on gage over one of the squared portions 31 to thus couple the receptacle to shaft 14 against independent turning. In order to prevent detachment ofsaid portion 124 from the adjacent squared portion, accidentally, a suitable means is, provided. To this end, said shaft 14 may have a continu ous groove surrounding the same as at 125 to be entered by a latch 126. This latch is receptacle 100 as through spaced barrels 127. Surrounding the latch 126 intermediate barrels 127 is an expansive coil spring" 128 engageable with a projection 129 on the latch so as to normally urge the latch through the said groove 125. A laterally extending lug 130 is provided on latch 126 to facilitate manipulation thereof to release the latch from the groove 125.

In practice, as stated, the inking device is disposed compactly Within the cylinder.

15 capable of movement independently thereof. Should it be necessary to ink the sheet 26, the handle 21 is moved to. an operative position externally oi the cylinder and the latch 126 is released from the groove 125 and the receptacle 100 vis slid longitudinally of shaft 14 so as to disengage the squaredportion of the tube at 124 from the adjacent squared portion of the shaft. It will be thus seen that in this condition, the

receptacle 100 as well as the brush'or applicator 10.2 is capable of sliding and rotatable movement on the shaft 14; relatively to the cylinder 15 and independently thereof. In such an instance, valve 109 being properly adjusted, one hand of the operator may grasp the handle 25 and the other hand of the operator may grasp the handle 121. Such handles may be moved relatively in order to move the brush 102 over the entire inner surface of the diaphragm 24. so

that the ink will flow through the perforations of said diaphragm and be absorbed by the ink mat 25. When the mat 25 has been sutliciently inked, valve 109 is closed and the rcceptacle 100 is moved longitudinally ot the shaft 14 so that its squared portion l2-lwill engage the adjacent squared portion of said shaft 14 and the latch 126 will spring into the groove 125. The handle 121 may then be lowered. Thus the inking device will be held against movement imlcpcndcntly of the cylinder and in contact disposition within the same.

\Vhcn the machine is in transit or out of use temporarily the parts are in the position shown in dotted lines in Figure 2. In order to use the machine, hooks 97 are disengaged from the eyelets 99 and thereupon the leaf 56 is secured with a level to the table 54 and thc basket 93 is lowered and books 97 engage in eyelets 99 to support it in a substantially horizontal and .receiving position. The sheets of paper or other material to be printed are arranged upon the table leaf 56. Withmtlte. gages '59 setrelatively to the width of.. 116' paper, and

with its stencil and ink niats properly arranged on the cylinder 15, such cylinder is turned in the direction of the arrows but the sheetsare fed manually intermediate basket 93, from which the same can he re-.

moved at will. It is clear that the. stencil, inking mat and blotter may be removed or replaced at will and thatduring such oper ation, or whenever otherwisedesired, the handle 83 may be turned so as to rock shaft 80 and cause cams 81 to depress the levers 73 and accordingly lower the platen rollers (37 and 68 and maintain them in a lowered position out of contact with the cylinders 15 and 16 until the machine is in conditon for further use and they have been restored to normal position through turning of said handle 83 in the reverse direction.
